水生昆虫的领地性

在大多数水生昆虫中，对领土性的研究几乎没有超越描述阶段，但一些领土物种已经得到了深入研究，并作为测试进化理论某些方面的模式生物。在简要介绍了一般的领土性之后，我回顾了水生昆虫的领土性的分类分布和类型，然后再深入研究更多的理论主题。水生昆虫的幼虫取食区域已被描述为若干目（双翅目、蜉蝣目、蜻蜓目、翼翅目、毛翅目），而成虫取食和交配区域仅在蜻蜓目（豆蛉和蜻蜓）和半翅目（水黾和纹虫）中有报道。我主要以多纳塔为例，更批判性地回顾了以下主题：(1)领土地位的决定因素和领土竞争的结果，(2)领土信号和线索，(3)种间领土性的持久性，以及(4)激烈的特征位移。利用水生昆虫在这些领域都取得了重要进展，但持续存在的方法问题也阻碍了进展。我为研究领土性提供了一些一般性建议，并通过确定需要进行更多研究的领域来结束。
Research on territoriality has barely progressed beyond the descriptive stage in most aquatic insects, but some territorial species have been studied intensively and served as model organisms for testing certain aspects of evolutionary theory. After providing a brief introduction to territoriality in general, I review the taxonomic distribution and types of territoriality reported in aquatic insects, before delving into more theoretical topics. Larval feeding territories have been described in aquatic insects of several orders (Diptera, Ephemeroptera, Odonata, Plecoptera, Trichoptera), while adult feeding and mating territories have only been reported in Odonata (damselflies and dragonflies) and Hemiptera (water striders and ripple bugs). With mostly Odonata examples, I review the following subjects more critically: (1) determinants of territorial status and the outcome of territorial contests, (2) territorial signals and cues, (3) persistence of interspecific territoriality, and (4) agonistic character displacement. Important advances have been made in each of these areas using aquatic insects, but persistent methodological issues have also impeded progress. I offer some general advice for studying territoriality and conclude by identifying areas where more research is needed.
